The value of IO Switch Status is a bitwise summation of 2 function settings; convert the decimal value to binary to see the status
of each bit. To activate one or both bits, write the sum of their decimal (or hex) values to the register.
Parameter IO Switch Status supports the following settings (other bits are ignored):
Bit Function
0 Actuation switch
8 Observe or ignore
instrument safe state*
*) See parameter Special parameters - Control Mode
Immediately after powering-up, both bits are inactive.
